Benefits of technology

The present invention provides a nasal mask that overcomes the drawbacks of the prior art. The mask has a main body with an inner and outer rim, and an annular seal ring. The mask also has a head strap and a nose unit with nasal prong members and engaging plates for attachment to the mask. The air supply unit is connected to the outer rim. The technical effect of this design is to improve the seal and comfort of the mask for users, allowing for better air flow and reduced leakage.

Problems solved by technology

When the conventional nasal mask is worn by a user and an external force is acted on the head strap 2, the main body 1 is adversely affected such that the nose unit 3 may be disengaged from the main body 1, and air may leak from the engaging hole 103 to result in insufficient supply of air, thereby influencing the sleep quality of the user.

Abstract

A nasal mask includes a main body having an annular inner rim and an annular outer rim, two connection members respectively connected to two opposite sides of the main body, and two engaging holes each formed in proximity to a junction between one connect ion member and the main body. The inner rim is formed with an annular shoulder and a seal ring that projects from the shoulder. A head strap unit has two opposite ends connected to the connect ion members. A nose unit includes a main plate having a peripheral edge abutting against the shoulder and the seal ring, two nasal prong members connected to the main plate, and two engaging plates to engage the engaging holes. An air supply unit is connected to the outer rim.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The invention relates to a medical device, and more particularly to a nasal mask.[0003]2. Description of the Related Art[0004]Referring to FIGS. 1 and 2, a conventional nasal mask is shown to include a main body 1, a head strap 2 connected to two opposite sides of the main body 1, a nose unit 3 connected to an inner side of the main body 1, and an air supply tube 4 connected to the main body 1 opposite to the nose unit 3. The main body 1 is made in one piece from silicone, and has an inner wall 101, and an outer wall 102 opposite to the inner wall 101. The inner wall 101 defines an engaging hole 103 to receive engagingly the nose unit 3. The outer wall 102 defines a connecting hole 104. The air supply tube 4 is connected to and is positioned in the connecting hole 104.[0005]When the conventional nasal mask is worn by a user and an external force is acted on the head strap 2, the main body 1 is adversely affected such th...
